How to terminate the command in shell script

[kemparaju]

Hi,

How to terminate the command in shell script, which is expecting Ctrl+c to get terminate. For example my shell script is

cat /dev/input/event1 > event1.txt
cat /dev/input/event2 > event2.txt
cat /dev/input/event3 > event3.txt


but it is not executing 2nd command, because first command will be waiting for the input of Ctrl+c to get terminate. But I dont want to press Ctrl+c manually.
Is there any way to execute these 3 commands without manuall input.
Please help me out.

Thanks
Kemparaju

Start in background, wait a bit, then send it a kill, ie:


cat /dev/input/event1 > event1.txt &
pid=$!
sleep 1
kill $pid
